lMPRGVEWlENT lbl THE CUTTlNG GEAR OF STRAW-CUTTE RS.

Specification forming part of Letters Patent- No. Hibfifir'i, dated November 8, 1853.

To all whom it may concern:

Be it known that we, JOHN JONES and ALEX- ANDER LYLE, of Rochester, in the county of Monroe and State of New York, have invented a new and useful Improvement; on a Machine for Cutting Straw; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed.

drawings, making a part of this specification,

in which- Figure l is a perspective View of our machine. Fig. 2 is a View showing the shaft and heads, with the knives attached to the heads, as seen when looking directly down upon it. Fig. 3 is a section through A B, Fig. 2.

' (J U,Fig. 1,shows the frame of our machine. 1), Fig. 1, shows the inside of the feed-box. E, Fig. L, shows the driving-wheel.

F, Fig. 1, shows the wrist of a crank which is attached to the driving-wheel E.

G, Fig. 1, shows a pinion into which the driving-wheel E works.

E, Fig. 1, shows a shaft to which the pinion G is attached.

I, Fig. 1, shows a balance-wheel which is at tached to the opposite end of the shaft H.

J, Fig. 1, shows one of the heads to which the knives are attached, and which is firmly fixed to the shaft H.

K, Fig. 1, shows a segment of a flange, ora part of the head opposite the head J.

L, Fig. 1, shows one of the knives.

hIi,Fig.1,shoWs theknifeoppositetheknifeL.

. N, Fig. 1, shows a segment of a flange which .forms a part of the head J. 0, Fig. 1, also shows a flange, which is cast on and forxnsa part of the head J. The head opposite J is fixed with flanges, in the same manner as shown at N and 0.

K shows a segment of a flange opposite the flange N. The knives L and M are bolted onto the inside of the segments of flanges N and O and to the segments of flanges opposite,which segments of flanges form a part of the heads.

P P, Fig. 1, shows a part of the month-piece to our machine.

Q, Fig. 1, shows a not on one of the bolts, by which one end of the knife M. is held onto the inside of the segment of a flange, O.

B, Fig. 1, shows the head of a bolt by which one end of the knife L is held onto the inside of the segment of a flange, N.

S, Fig. 1, shows the head of one ofthe bolts by which the other end of the knife L is held onto the inside of the segment of a flange, K.

T, Fig. 1, shows one of the set-screws by which the knives are regulated. There are four set-screws, which are fixed in the same manner, one at each end of each knife.

U,Fig. 1, shows a part of the npperfeed-rol].

V, Fig. 1, shows one end of the feed-roll U.

\V, Fig. 1, shows a pinion which is attached to one end of the feed-roll U.

X, Fig. 2, shows the shaft which is shown H, Fig. 1.

Y, Fig. 2, shows the head shown J, Fig. 1. Z, Fig. 2, shows the head opposite the head J:

a, Fig. 2, shows the knife shown M, Fig. 1.

b, Fig. 2, shows the knife shown L, Fig. 1.

c, Fig. 2, shows the flange shown N, Fig. 1.

d, Fig. 2, shows the flange shown 0, Fig.1.

0, Fig. 2, shows the flange a part of which is shown K, Fig. 1.

f, Fig. 2, shows the head of the set-screw shown T, Fig. l. g, Fig. 2, shows the head of a set-screw opposite the set'screwf. The setscrewsfand g are for the purpose of regulating the knife a. The knife I) is regulated by set-screws working against the back of the knife at each 'nd, in the samemanner as shown atf and g.

h and t, Fig. 2, show the heads of the bolts by which the knife a is held onto the inside of the flanges which are attached to the headsY and Z.

jand 70, Fig. 2, show the heads of the bolts by which the knife b is held onto the inside of the flanges c and c.

Z, Fig. 1, shows a section of the shaft shown B, Fig.- 1, and X, Fig. 2.

m, Fig. 3, shows the head shown J, Fig. 1, and Y, Fig. 2.

a, Fig. 3, shows a section of a segment of a flange shown 0, Fig. 1.

0, Fig. 3, shows a section of a segment of a flange shown N, Fig. 1.

19, Fig. 3, shows a section of the knife shown L, Fig. 1.

q, Fig. 3, shows a section of the knife shown M, Fig. 1.

1', Fig. 3, shows the head of the set-screw which is shown T, Fig. 1.

s, Fig. 3, showsthc not which is shown Q, Fig. l.

Now, it will be seen that by turningthedriving-wheel E the pinion G is caused to revolve, and the pinion Gr being attached to shaft H the heads and knives are caused to revolve, and the straw being put into the feed-boxD is carried through the mouth-piece by means of feed-rolls and is cut in the ordinary Way. By means of the set-screws the knives are placed so as to Work close to the mouth-piece P P, and by having the knives bolted onto the inside of the segments offlanges, as has been described, it is rendered impossible for the knives to overreach and cut into the mouth-piece, provided they work loose while operating the machine. It has been found by experience that when the knives are bolted to the outersurface of the flanges or heads they Work loose and overreach and cut in or lock onto the monthpiece', and thereby break the knife or some other part of the machine; but by placing the knives on the inner surface of segments of flanges which form a partof the heads, as has been described, the difficulty of the knives overreaching and cutting in or locking onto the mouth-piece and breaking the machine is entirely overcome, which is the advantage of our invention.

Having thus described the construction and operation of our machine, We do not claim the knives, heads, or flanges Which form apart of the heads, separately; but

What we do claim, and desire to secure by Letters Patent, is

The combination of the knives and segments oftlanges, (which are attached to and form a part of the heads,) the knives being placed on the inside of the flanges instead ofthe outside, in the manner and for the purpose substantially as herein described and set forth.
